Re: Incident light metering

>Well I sure don't want to start a row over this, but I believe someone missed it on describing the standard reflectance factor upon which incident light meters are based. Standard reference subject, usually considered the average subject in a scene, is typically 18%gray. At least that is what Minolta and Sekonic use. 

So did Ansel Adams ["The Negative", p24 (1981)]. Kodak sells 18% reflectance gray cards, which in effect change a reflectance meter to an incident light meter.

As an aside, my most serious photography is wildflowers. My very fancy TTL metering SLR consistently overexposes, because it sees the flower along with lots of soil or branches which are in deep shade. The sunny 16 rule actually works better if the sun is out and my shadow is shorter than I am.

Similarly, when I decide to relax and become a stereo photographer, the rule lets me take nicely exposed pictures with my meterless Wirgin. [Now if I just had a stereo camera with a rangefinder.]
